便携式镗孔机器
摘要：
便携式镗孔机器(100)，包括：-传动单元(101)，所述传动单元包括具有旋转轴线(B)的第一电动马达(103)以及将由所述电动马达(103)施加的运动分配到刀具轴(105)的分配块(104)，该刀具轴(105)支撑用于镗孔和焊接的装置并具有旋转轴线(C)；-中央单元(102)，包括用于推进所述刀具轴(105)的支撑轴(109)以及适于管理所述推进的第二中央电动马达(110)，所述支撑轴由空心圆柱管形成，且内部包括外螺纹的螺纹管(111)；-用于将所述传动单元(101)和所述中央单元(102)联接和断开的装置(108，114)；以及-所述螺纹管(111)的推进系统，被配置为用于将由所述电动马达(110)施加的旋转运动转换为所述螺纹管(111)沿所述轴线(C)的直线运动。
摘要（英）：

Portable boring machine (100) comprising: - a transmission unit (101) comprising a first electric motor (103) having an axis of rotation (B) and a distribution block (104) of the motion imparted by said electric motor (103) to a tools shaft (105) supporting means for boring and welding and having an axis of rotation (C); - a centralized unit (102) comprising a supporting shaft (109) for advancement of said tools shaft (105) formed by a hollow cylindrical tube internally comprising an externally threaded screw tube (111), and a second centralized electric motor (110) adapted to manage said advancement; - means (108, 114) for coupling and decoupling said transmission unit (101) from said centralized unit (102); and - an advancement system of said screw tube (111) configured for converting the rotary motion imparted by said electric motor (110) into straight linear motion of said screw tube (111) along said axis (C).
